As soon as default init for CON gets in this won't work right anymore - these must come last, not first.
This commit contains all the trivial cases with no inheritance concerns.
.def is not the right place for this - it needs to run very early in the process, before scripted actors are loaded, so doing this stuff there means that half the initialization has to be postponed and error reporting is sub-par.
These are now part of RMAPINFO which gets parsed as one of the very last things - it is also where GZDoom is doing some of these things.
The better error reporting also allowed fixing some errors in these definitions.
